1995 e320 running hot

[chiwanga]

I'm pulling my hair out over this car running hot. As long as your moving, it stays normal, but as soon as there is a load on the engine or a long traffic light, the temp creeps up to 110 and kicks on the aux fans. It has been verified that there is no compression leaking into the coolant, it has a new radiator, 50/50 Mercedes coolant and water, a new fan clutch, and nothing has made a difference. What else would you suspect?
